ZL Rotary lobe blower• Flow rate from 10 - 5,700 cfm• Pressure from 0 - 14.5 psig• Vacuum up to -7.25 psig

High performance and low costsThanks to the simplicity and the tested design of the lobe blower, it is the ideal choice for difficult environments around the world that have limited supervision requirements, providing the exact amount of air requested by the application.

Methods of operation • Pressurised (up to 14.5 psig)• In a vacuum (up to -7.25 psig)

A simple, complete and high-quality solution.The rotary lobe volumetric blower is developed for low pressure compressed air applications, with operating pressures ranging from 0-14.5psig

This type of blower is also suitable for compressing Biogas, CO2, Nitrogen and operating in a vacuum

Atex versions are also available in stainless steel for food and pharmaceutical applications

The blowers can also be supplied in a Plug and Play version, i.e. with an electrical panel with a Y/D starter or inverter, inside the blower

Advantages

A complete package for all applicationsThe ZS blower is designed to guarantee maximum product safety. It ensures a continuous and long-term supply of oil-free air, it is highly reliable and energy-efficient in all your applications, and has the lowest possible operating costs.

Maintenance costs and downtime are reduced due to the innovative technology of the screw blower. The blower is also available in a Plug & Play version, with an on-board ready-to-use Y/D starter or inverter.

WASTEWATER TREATMENT• Lower noise, lower supply-air

temperature and lower vibrationsthan the lobe blower

• Wide pressure range and flow rate

DILUTED PHASE PNEUMATIC TRANSPORTATIONMinimise energy costs, up to 80% of the cost of running a blower

FERMENTATION• Oil-free certified air• Wide pressure range and

flow rate

NON-WOVEN FABRIC• Adjustable flow rate to determine

the characteristics of the fibres• Energy efficient blower to reduce

the running costs of this 24/7 activeprocess

• Adaptable installation without theneed for noise prevention measures

Applications

ZS Oil-free screw blower• Flow rate from 120 - 5,500 cfm• Pressure from 0 - 22 psig

ZBVariable Speed Direct Drive Centrifugal blower with magnetic bearings• Flow rate from 900 - 7,000 cfm• Pressure from 0 - 19 psig

Proven reliabilityLow pressure compressed air is the basis of many production processes. A reliable and constant flow is essential and the air quality must be high. Aeration for waste water, printing, air separation, fermentation and processing of non-woven fabric do not tolerate product contamination.

The Atlas Copco ZB range is the ideal choice for meeting the high demands of these processes. This range offers a complete package that comes with all the components perfectly synchronised.

ADVANTAGES OF THE VSD SYSTEM• Constant system pressure

guarantees stability for all processesthat use compressed air

• Absence of current peaks duringstart-up:- Unlimited start and stop cycles- No risk of current peaks during

start-up

INTEGRATED - THE ONLY EMC TESTED AND CERTIFIED SOLUTION:• No emissions from other equipment• Synchronous motor with permanent magnets• Full range of Flows without “flow gaps”• 100% Turndown as the only blower that continues to run with blow off

EXCEPTIONAL RELIABILITY AND EFFICIENCY OF MAGNETIC BEARINGS:• Capable of withstanding sudden

Surge conditions• The contact-free design offers

unlimited start-stop cycles• Friction-free operation for maximum

efficiency and guaranteed reliability

Advantages package

Easy installationThe ZE/ZA compressor is supplied as a ready-to-use all-in-one package and includes a powerful controller and an optional integrated after-chiller (internal or external depending on the model). The completeness of the supply eliminates the need for additional components and minimises installation work, consequently saving time and money.

The ZE/ZA compressor is immediately operational, as it is built to be easily integrated into the existing compressed air network.

ZE/ZAOil-free single-stage screw air compressor• Flow rate from 300 - 4,500 cfm• Pressure from 0 - 60 psig

GLASSBLOWING• Higher pressure ratio for mould

cooling • Maximum quality thanks to totally

oil-free air certified as Class 0 Reduced energy consumption for continuous operation

DENSE PHASE PNEUMATIC TRANSPORTATION• Reduction of energy costs, as they

are up 80% of the running cost of acompressor

• Compressors can also be installedoutdoors. They can be exposeddirectly to the weather and can bekept near the silos for unloading

MINERAL SECTOR• Improved energy efficiency

and productivity with lowenvironmental impact

• Minimum machine downtime andmaintenance costs, thanks to the innovative technology of single-stage screw compressors

FERMENTATION• Reduction of energy costs kept to

a minimum, as they are up 80% ofthe running cost of a compressor

• Reduced machine downtimeand maintenance costs, thanksto innovative screw compressortechnology

• Extremely wide pressure rangeand flow rate

Applications

ZMCentrifugal blower with side channels• Flow rate from 500 - 32,000 cfm• Pressure from 0 - 20 psig• Vacuum up to -7.25 psig

Great energy efficiency in the compression of air or gas including in a vacuum.The ZM series is a centrifugal blower with oil-free compression and a variable number of stages, depending on the desired flow rate and pressure.

The blower is air cooled and is designed to be used with an inverter and based on a pressure range of up to 20 psig (under pressure), -7.25 psig (in a vacuum) and a flow rate upto 32,000 psig for air or gas.

Technologies at the service of industriesAtlas Copco low-pressure solutions are ideal for the following industries:

SMARTLINKDATA MONITORING With SMARTLINK service, compressor and blower data can be monitored in real time by PCs and smartphones.

Continuous monitoring allows for planning of maintenance operations and optimizes the use of compressed air, leading to an increase in energy efficiency and, as a result, generating savings in terms of time and money. The service can also automatically provide energy reports in compliance with ISO50001. Thanks to notifications on smartphones, users can be informed promptly about the conditions of the compressor room.

The SMARTLINK Notifier app is available at the App store and Google Play Store.
